in the quest for the legendary with the right nature, cuz i wanted to use it for pvp...

i was wondering could we somehow see it's nature or it's iv's before catching it??? maybe a ditto? but would it copy the iv's? would that work on legendary's? also would there be some pokemon able to somehow give information on what nature or iv's the legendary pokemon might have?
